The world’s first north seeking solid state Gyro. Designed for driller operation.


Champ Gyro™ is the worlds first innovative north seeking solid state gyro system that allows users to take high accuracy singleshot, multishot or orientation measurements at the push of a button.

It’s tough, reliable, requires no starting azimuth and is ready to survey within minutes. The Champ Gyro is the smallest and lightest North Seeking gyro on the market Champ Gyro offerings the ultimate in simplicity, performance and productivity.

Replace conventional magnetic singleshot surveys by surveying each time you pull core with the Champ OSA and increase hole positional certainty whilst decreasing costs through reduced rig downtime.

The Champ Gyro has a robust design capable of performing surveys for both diamond and RC holes in both surface and underground environments.

Depth stations can be assigned manually or wirelessly via AMT’s Electronic Depth Counter.

Upon download, quality control functions can be applied and data viewed on screen at the rig site or uploaded to Axis onTrack™ Survey Analysis Software for further features such as enhanced analysis, survey and 3D graphical views as well as report generation. 

Housed in 36mm (1.41”) running gear the Champ Gyro measures 1.64 meters (5.38ft) long and weighs less than 7kg (15.43 lbs).

Battery modules have a 15-hour life and with two supplied as standard you will never run short on power.
